Atom-Editor: Rubocop doesn't work with atom

Question

I was trying to connect rubocop to atom, but received the error:

linter-registry.js [sm]:144 [Linter] Error running RuboCop Error: /usr/lib/ruby/2.3.0/rubygems/dependency.rb:319:in `to_specs': Could not find 'rubocop' (>= 0.a) among 16 total gem(s) (Gem::LoadError)

    at next (<anonymous>)
    at step (/home/kurilovichay/.atom/packages/linter-rubocop/src/index.js:11:273)

which rubocop returns:

/usr/local/bin/rubocop

can someone assist with that?

Answer 1

It seems that you're using rvm to manage your environment. What i did to get it to work was follow the instructions on their repo: https://github.com/AtomLinter/linter-rubocop#settings

# make sure I'm in the global gemset
$ rvm gemset use global
# install the gem
$ gem install rubocop

configure atom to use the global. Edit your atom's config file (config.cson) and add

*:
  "linter-rubocop":
    executablePath: "~/.rvm/gems/ruby-2.3.1@global/wrappers"
  "linter-ui-default": {}

Note: make sure that the ruby version is the one you're using.
